Abstract
Three mononuclear metal complexes, [{PO2(NH2Py)2}2M] [2Py = 2-pyridyl; M = Zn (1), Ni (2), Co (3)], have been synthesized by reacting metal nitrates with tetrakis(2-pyridylamino)phosphonium chloride, [P(NH2Py)4]Cl, under solvothermal reaction conditions. The ligand, [P(NH2Py)4]Cl, is hydrolyzed in the reaction medium. All of the complexes are isostructural and show an octahedral geometry around the metal ion. A coordination polymer, [{P(NH2Py)4Cu2Cl4}ClO4]∞ (4), was also obtained by treating [P(NH2Py)4]Cl with copper perchlorate hexahydrate at ambient temperature. All of the complexes were characterized by standard analytical techniques. The solid-state structures of 1–4 were established by single crystal X-ray diffraction analysis. The optical properties of 1–4 have been investigated.
